Continuity mistake: When Charlie and Hurley are talking to Jack about the water, Jack then shouts something like, "I'm not making any decision," and in the background two people walk by - they move from right to left. After a cut to Charlie and Hurley when Hurley asks "Why?" it cuts back to Jack, and the same two people walk from right to left again.
Continuity mistake: When Sayid goes over to Shannon to help her with her luggage her trunk falls down open and some clothes fall out. Then Sayid picks up some shirts. But when it cuts to Shannon grabbing them from him he is holding fewer and different looking shirts than he picked up first.
Continuity mistake: On the airplane, when Kate lifts the glass of juice with her handcuffed hands, in this close-up the cuff round her right wrist has the single bar facing out. However, when the turbulence hits, in another close-up of her hands, the same cuff is on the opposite way, it now has the double bar facing out.
Continuity mistake: On the airplane, the same passengers are seen in numerous shots with different main characters, and purportedly Kate and Marshal Mars (row 25) are in the same cabin on the opposite side of Jack, Rose and Locke (rows 23 & 24), yet are not seen in shots where they should be seen - though in shots of Jack and Rose, during the turbulance, the same woman and man (behind Locke) fly up as in the Kate and marshal shot. Some examples: When Kate and the marshal are shown during the turbulance, note the red-haired man with the black shirt beside the marshal and other men behind, and in one shot of Kate and the marshal, a woman and man both fly up to the ceiling of the cabin. In some shots of the turbulance, when the red-haired man is seen, the marshal and Kate are gone, replaced by other passengers. Just before the tail section breaks off, men behind the red-haired guy have either changed seats or disappeared, and so forth. Row numbers seen on the luggage compartments overhead are inconsistent with passenger seating. Such as when the tail section breaks off, the man is pulled out from row 26, yet the number above reads 13, or when Claire boards the numbers overhead are 20, 21, 22, yet Jack is in row 23, which is the second row behind the wall. The interiors of the Oceanic airplane also significantly differ in various shots. One example - the seats on the airplane have blue square velcro coverings on the passengers' seat headrests, and long, wide magazine racks on the divider wall behind Locke, but when they carry Locke onto the airplane, they don't exist.
Continuity mistake: Sayid wears a black tank top when he speaks at Boone's burial, and it has a wide shallow tear and small hole at the collar. When he walks away with Jack, who is complaining about Locke, though the style of top is identical, now the tear is narrower and deeper, and the hole is bigger. Throughout this episode the tear, on the tank top Sayid wears, alternates, and the hole even disappears.
Continuity mistake: Just as Sayid walks out of the building (number on both doors is 815), the white van pulls up. When Sayid gets in, in the exterior shot, the door he opens is opened to Sayid's left, but in the next interior shot, the door is opened to Sayid's right (the door to his left is closed). In this shot the building is seen behind Sayid - note the number 815 on both doors have vanished, and the chipped wall paint differs.
Continuity mistake: When Shannon is looking for Boone but instead finds his "jungle pal" Locke, he is gutting his dinner and gets blood on his face. The blood on Locke's face repeatedly changes, such as in one shot there's a small clot of blood beside his eye, and in another shot the blood is lower and larger.
Continuity mistake: On the beach, when Shannon questions Boone about his and Locke's whereabouts everyday, Boone wears a sleeveless tee shirt with large Asian characters on the front. Then, when Boone kneels beside Shannon the entire design actually disappears.
Continuity mistake: When Kate leans over the unconscious marshal he wakes and chokes her, and when Jack subdues him the marshal's large head bandage falls off. When Jack squeezes water into the marshal's mouth, the bandages are wrapped perfectly round his head, yet when Kate stands up the bandages are off again.
Continuity mistake: When Claire is holding Aaron talking to Locke, she says "I can't believe he is still sleeping" and they show him sleeping. She then asks Locke if he wants to hold him and then hands Aaron to Locke. His eyes are wide open. Then you see Locke obviously holding a doll in the next shot and they are talking about him still being asleep. Locke then hands Aaron to Charlie and the eyes are again wide open and they are still talking about him being asleep.
